10 Horror Movies With Terrifying Surprises

1980's Terror Train is a picture that has a deranged, masked killer tormenting a group of college kids during a New Year's Eve party that's bizarrely being held on a train.

As for said killer, that's former classmate Kenny Hampson (Derek MacKinnon), who had been locked up in a psychiatric hospital for the past three years.

For those wondering why Kenny had been locked up during those years, that's because the poor fella had an absolutely horrendous prank pulled on him; a prank so traumatic, it caused him to have a mental breakdown and ultimately vow revenge on those who'd wronged him.

The opening scene of Terror Train sets the stall for all of this, with the mild-mannered Kenny lured into a room on the promise of getting laid. It's Jamie Lee Curtis' Alana who is reluctantly convinced to trick Kenny into said room, and it's only once the lights are turned on that Kenny has the truly awful surprise of discovering he's been fondling a mutilated dead body.

Yep, dead body. Like, a proper corpse.

While Terror Train doesn't reveal its masked killer's identity until its final act, you find yourself genuinely hoping that it is Kenny carrying out these murders - for he more than deserved some slice of revenge.
